Trying to use a barcode library with Composer and CI4

Hi

I could successfuly install (in a CI4 install in subfolder) the following libraries with Composer: dompdf and guzzlehttp
Then, I use both in the Controller, etc.

Code:

...
...
use Dompdf\Dompdf;
use GuzzleHttp\Client;
...
...
$client = new \GuzzleHttp\Client(['http_errors' => false]);
$dompdf = new Dompdf();
...
...

But I cannot make the same with the following one:

https://github.com/picqer/php-barcode-generator

I've installed with this

Code:

composer require picqer/php-barcode-generator

Then I use with

Code:

use Picqer\Barcode;
use Picqer\Barcode\BarcodeGeneratorPNG;

But when I try to use it, CodeIgniter does not find it

Code:

$generator = new Picqer\Barcode\BarcodeGeneratorPNG();

Class 'App\Controllers\Picqer\Barcode\BarcodeGeneratorPNG' not found

I've checked the "vendor/composer/autoload_psr4.php" file to see the namespaces.

Any suggestions ?

Thanks a lot
